Re: Is my service table for csv file correct ?

These four :
+WRITE:0,3,1,1,2
+WRITE:0,3,3,1,2
+WRITE:0,3,4,1,2
+WRITE:0,3,5,1,2
are affecting the 0x2902 in order to tell server that client is ready to receive notifications. The values are sent with
+WRITE:0,3,2,,20
+WRITE:0,3,3,,20
+WRITE:0,3,4,,20
+WRITE:0,3,5,,20

BLE communication through AT command

Hi,
Is it possible to manage entire BLE communication between an STM32 MCU and the ESP32 UART using only AT command ?
If yes, is there any example ?

Thanks

Change Propertie of Device Name from READ to READ / WRITE

Hi All,
I'm using the ESP32, for a BLE application and I need to change the properties of an existing characteristic "Device Name" from READ to READ / WRITE.
I also need to change type of the Value displayed from HEX to UTF-8.
I didn't find the right way to do this.
Can anyone help ?

Thanks
